Title: Cooled mechanical seal
IPC: F16J15/34
Filed: 1972-11-22
Abstract: 1417135 Screw pumps F BURGMANN [trading as FEODOR BURGMANN JNR ASBEST--U PACKUNGSWERK] 22 Nov 1972 [24 Nov 1971 7 July 1972] 54124/72 Heading F1C [Also in Division F2] The carrier 2 of an end face seal is formed with a helical thread 23 closely surrounded by a helical thread 24 on the inner surface of a sleeve 18 secured to the housing 9. The threads 23, 24 are opposite handed and act as a.pump. An annular duct 27 is defined by the surface 26 on the sleeve 18 and a surface 25 on the carrier 2, the surfaces 26 and 25 being convex and concave arcs respectively in longitudinal section. In operation, coolant in the system is'drawn by the pump 23, 24 from a space 17 into a space 19 between the sleeve 18 and housing 9 where it is discharged through the passage 27 to the chamber 16 surrounding sealing rings 1, 6 and back again to the space 17. The reduction in cross-sectioned area if the duct 27 towards the space 16, which increases the coolant velocity, may be augmented by reducing the distance between surfaces 26, 27 as they approach the space 16. In the modification shown in Fig. 2, the flow direction of the coolant is reversed, the coolant being drawn into the space 16 from the annular duct 14A whose discharge end is formed similar to that of duct 27, Fig. 1, to accelerate the coolant exit approaches space 16. The pump performance, i.e. discharge pressure and throughput, may be varied automatically in response to changes in coolant temperature by making the parts having the threads 23, 24 of materials having different coefficients of thermal expansion thus, one part, preferably that formed with the thread 24, may be of a nickel-iron alloy and the other part may be of steel, ebonite or P.T.F.E.

Title: Cameras
IPC: G03B17/52
Filed: 1970-11-23
Abstract: 1316506 Cameras POLAROID CORP 23 Nov 1970 [2 Jan 1970 1 May 1970(2) 11 May 1970] 55630/70 Heading G2A A camera contains a plurality of film units 182 which are sequentially exposed, processed, and then passed to a storage chamber 136, the space in the chamber being variable according to the number of units to be accommodated, and means also being provided for viewing a processed unit if required. The extensible camera of Fig.1 is shown in its erected operative position with its film door in the open or loading position. The section 12 contains a number of members 20, 22, 24, 26 by means of which the uppermost of a stack of film units is presented at an exposure station, and then transported by means of drawer 22 to the left so as to pass between rollers 186,188 and then back again to the right so as to enter into a storage space 136 below bottom wall 70 of drawer 22, in a similar manner to that disclosed in Specifications 1316502 and 1316503. The outer frame member 24 has at one end a cross piece 96, 98 in which is mounted a magnet 102, which acts as a coupling between member 24 and the inner frame member 20. A lever 28 is provided for breaking this coupling in order to open the camera for loading. A resilient plate member 134 is connected at its trailing end to cross piece 96, its other end remaining in contact with closure member 26 whether the camera is in its closed (Fig.5) or open (Fig.6, not shown) position. The space above plate 134 forms the storage space of variable volume. As the camera is moved from its open to its closed position, this space contracts until it is just sufficient to accommodate the film units therein. Thus the storage space is always kept at a minimum. The initial reciprocating movement of the drawer is to remove a dark slide which covers the film units. With the return movement of the drawer, the slide passes beneath roller 188, and the foremost film unit is ready to be exposed. After exposure, the drawer again moves to the left, taking the exposed film unit with it, so that it passes between the processing rollers. The dark slide remains behind, retained by a spring 77, eventually falling into the storage chamber as the drawer is drawn clear. The return movement of the drawer now passes the exposed film unit below the lower roller 188, and it in turn will fall into the storage chamber when the drawer is next drawn to the left with the next exposed film unit. At this moment, however, while it still remains in the drawer, it may be viewed, if required, by opening the camera to the Fig.1 position, and either inspecting it in situ or by removing it for viewing, and then replacing it. Fig.12 (not shown) is a modified arrangement by means of which the invention can be applied to a non-extensible camera.

IPC: B01D53/02
Filed: 1973-12-03
Abstract: 1430855 Removal of phosgene from halogenated hydrocarbons DOW CHEMICAL CO 3 Dec 1973 55889/73 Heading C2C  An anhydrous gas stream, e.g. chlorinated hydrocarbon, is purged of phosgene by contacting the stream with activated alumina of surface area at least 20 sq. metres per gram at 110-200‹ C. under essentially anhydrous conditions i.e. less than 100 p.p.m. of water. The process is particularly useful for purifying a stream of methyl chloride containing HCl. The activated alumina is preferably obtained by heating Al 2 O 3 .H 2 O to at least 300‹ C. to remove at least a part of the water of crystallization to re-orientate the crystalline structure to produce γ-Al 2 O 3 . In the example the product stream from the thermochlorination of methane is treated to remove phosgene.

Filed: 1966-12-16
Abstract: 1,149,060. Temperature alarms. E. H. TAYLOR. 18 Dec., 1967 [16 Dec., 1966], No. 56516/66. Heading G4N. [Also in Division H1] A temperature sensitive alarm comprises a thermally sensitive magnetic device including a permanent magnet mounted in a surrounding housing, the housing or part thereof being formed of a material having a Curie temperature below the temperature at which the magnetic properties of the permanent magnet are affected, the device being arranged to actuate a warning device by induction of an electric current in the warning device at temperatures either above or below the Curie temperature. The arrangement of the permanent magnet and the housing is such that either below or above the Curie temperature of the material a locally intense magnetic field is produced by the device. A cylindrical permanent magnet 1 is mounted in a pot 2 of " Curie material " and surrounded by an aluminium spacer 3. This device acts as a normal pot magnet until the Curie temperature is passed whereupon the magnetic circuit through 2 is broken and the annular magnetic field no longer exists. In another embodiment (Fig. 2, not shown) a polepiece (4) of " Curie material " is provided on the magnet 1 to give a device working in the same way. Another series of devices is disclosed which work in the opposite way, i.e. they have no effective magnetic field at room temperature but exhibit a magnetic field once the Curie temperature is passed. In one embodiment (Fig. 3, not shown) the device is identical in shape with that shown in Fig. 1, but the spacer 3 is made of the " Curie material ". In other embodiments (Figs. 4 to 8, not shown) combinations of aluminium spacers, polepieces and " Curie material " keepers are employed to give pot magnets and shallow-pot magnets, some having bolted keepers. The pot magnets may be used to form temperature sensitive electric switches or fluid valves, whilst auxiliary heating coils may be used to heat the magnets. The " Curie materials " may be nickel/iron, copper/nickel, pure nickel, "Nilo" (RTM) or Ferroxcube Mn-Zn ferrite whilst the permanent magnet may be Alcomax III (RTM).

Title: Method and Apparatus for Bending Workpieces.
IPC: B21D7/024
Filed: 1967-12-15
Abstract: 1,183,740. Angular bending. HILGER MASCHINEN-UND APPARATE-BAUANSTALT m.b.H. 15 Dec., 1967 [30 Dec., 1966], No. 57116/67. Heading B3E. A method of bending an elongated workpiece in a machine having a rotatable bending template, comprises arranging the workpiece tangentially of the template and in contact with a slidable guide carried on the periphery of the template, clamping the workpiece to the machine frame at the side of the guide remote from the intended bend and pivoting the template to deform the workpiece into a uniform arcuate path described by the guide element. An apparatus for carrying out the method comprises a body 10 on which the template 13 is mounted for rotation about a vertical pivot pin. The template comprises two parallel plates 14 and 15 between which are a number of rollers 18, each roller being rotatable about its own axis and its distance from the pivot pin being continuously adjustable. The part of the template adjacent the first roller 16 is extended radially outwards to form a mounting for a roller 17. The rollers 16, 17 and 18 all have an arcuate or V-shaped peripheral groove to suit the workpiece being bent. The end of the workpiece is held between hydraulicallyoperated clamping jaws 19 and 20, which are rotatable about an axis parallel to the pivot pin and the part projecting through the bending rollers 16 and 17 is curved to the radius of the template when the template is rotated by an hydraulic drive unit in the body 10. The rollers may be replaced by sliding shoes. For bending tapered tubes, the thicker end of the tube is held in the clamping jaws and the bending rollers 16 and 17 are spring-loaded together, to remain in contact with the tube as they move along it. If the bend to be produced is not exactly circular, the positions of the rollers 18 can be adjusted accordingly.

The laminations form an E-shape and the lugs are received in clamp rings 11.
Patent GB-1287921-A (GB)
IPC: B66B1/18
Filed: 1969-11-24
Abstract: 1287921 Lift control systems WESTING- HOUSE ELECTRIC CORP 24 Nov 1969 [17 Dec 1968 (2)] 57375/69 Heading B8L In a multicar lift control system scanning means operates continuously to detect the position of cars and registered calls, and cars travelling in a first direction are allocated a predetermined number of calls for said first direction on successive scans, but if a call is not allocated in this way (e.g. because each moving car has its quota of calls) a "demand" signal is generated which causes an available (i.e. uncommitted) car to be assigned to serve the demand, the allocations being continually reviewed and modified if necessary as the situation changes. The scanner is pulse driven and scans rapidly up and down in the order of the landings for car position, car calls and landing call signals which are processed by solid-state logic circuits so that the total calls allocated to a given car do not exceed the predetermined number. A landing call will be allocated to a car having a car call for that floor providing the car is close to that floor, otherwise it will be allocated in the normal way, that is, to the car closest behind the call. If that car has its quota it is allocated to the next car and so on. A demand created by failure to allocate a call as above is met by assigning the nearest available car, whether it is above or below the calling floor. Only one demand is dealt with on each scan, up calls being dealt with on up scans and vice-versa. Allocation is up-dated on each scan, and an alternative car distribution pattern can be simulated and acted upon if improved service would result. In addition to allocating calls the system operates to prevent cars answering calls under certain circumstances, e.g. if the car has its quota of calls or is fully loaded, or has already made a predetermined number of stops, and unless so prevented any car will stop for a landing call which it encounters in its travel, even if it has not been allocated to it. Distances are assessed by counters, normally one count per landing although more than one count may be used if landings are widely spaced. When no car is at a preferred floor (e.g. lower terminal) an artificial demand is created unless a car with few calls is near. Priority is given to down calls which have been unanswered for more than a predetermined time, by falsifying the position of a car in such circumstances so that that car appears to be more favourably placed to answer the call than it really is. Priority can also be given to a predetermined zone. The description incorporates Specification 1,196,981.

The female housing 12 includes a cylindrical hood 16 radially spaced from the contacts 26 and having internal polarizing slots 19. External ribs 30 define helical grooves forming a two-start thread with stops 44. Bosses 40 having inclined surfaces are formed in the grooves, being spaced by an interval 48 from the stops 44. The body 50 of the male housing 14 has passageways 56 for socket contacts, and polarizing ribs 60. A locking ring 76 of firmly resilient plastics material engages a groove formed in the body 50 to permit relative rotation without axial displacement. A collar 66 of the locking ring 76, radially spaced from the body 50, carries a pair of inward lugs 74. With the polarizing ribs 60 aligned with the slots 19 the bodies 12 and 14 are pushed together until the collar 66 can be rotated to cause the lugs 74 to enter and travel along the helical grooves of the female hood 16, drawing the mating parts closer together. When the lugs 74 are forced over the bosses 40 the collar 66 is distorted, snapping back with an audible click when the lugs 74 fall into the spaces 48, so indicating complete engagement of the connectors.
